Consider this query: ```sql select * from facetable where state = :state and on_earth = :on_earth and neighborhood not like '00:04' ``` Datasette currently gets confused and shows three form fields: https://latest.datasette.io/fixtures?sql=select+*+from+facetable%0D%0Awhere+state+%3D+%3Astate%0D%0Aand+on_earth+%3D+%3Aon_earth%0D%0Aand+neighborhood+not+like+%2700%3A04%27&state=&on_earth=&04= <img width="698" alt="fixtures__select___from_facetable_where_state____state_and_on_earth____on_earth_and_neighborhood_not_like__00_04__and_pyinfra_pip_py_at_current_·_Fizzadar_pyinfra" src="https://user-images.githubusercontent.com/9599/128656369-8af860bf-f7c1-4c9c-beba-1eb6887a8336.png"> But... if I run `explain` [against that](https://latest.datasette.io/fixtures?sql=explain+select+*+from+facetable%0D%0Awhere+state+%3D+%3Astate%0D%0Aand+on_earth+%3D+%3Aon_earth%0D%0Aand+neighborhood+not+like+%2700%3A04%27&state=&on_earth=&04=) I get this (truncated): addr | opcode | p1 | p2 | p3 | p4 | p5 | comment -- | -- | -- | -- | -- | -- | -- | -- 20 | ResultRow | 6 | 10 | 0 |   | 0 |   21 | Next | 0 | 3 | 0 |   | 1 |   22 | Halt | 0 | 0 | 0 |   | 0 |   23 | Transaction | 0 | 0 | 35 | 0 | 1 |   24 | Variable | 1 | 2 | 0 | :state | 0 |   25 | Variable | 2 | 3 | 0 | :on_earth | 0 |   26 | String8 | 0 | 4 | 0 | 00:04 | 0 |   27 | Goto | 0 | 1 | 0 |   | 0 |   Could it be as simple as pulling out those `Variable` rows to figure out the names of the variables in the query? {"total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} 959999095
